John Watson sees the speed and operator advantages of cooling

technotrans’ central cooling has been fitted on the world’s largest B2 Heidelberg press, the Speedmaster CD 74-L-Y-9+L-YY-L-X3(UV), at John Watson Printers in Glasgow.

Monday 26. January 2009 - technotrans’ central cooling has been fitted on the world’s largest B2 Heidelberg press, the Speedmaster CD 74-L-Y-9+L-YY-L-X3(UV), at John Watson Printers in Glasgow.

This allows the operators of the nine unit press with three coaters to keep the dampening under control and keep the area around the press cooler resulting in a better and cleaner atmosphere.

“This technotrans central cooling device is very important for quality but more so for speed. We can run at 15,000sph confidently, knowing that the viscosity of the ink will be better and that we will achieve good and consistent ink transfer,” says Tom Lightbody, production schedule manager.

This marks the company’s debut with centralised water-cooling and Mr Lightbody comments that there is a difference in conditions now from one side of the pressroom to the other.

The company is a long term user and fan of technotrans’ equipment and he says that ancillaries and consumables conditions do make a big difference to printed results. The company likes to store paper in the pressroom for 48 hours before use to ensure it is stabilised.

John Watson operates in a very quality-conscious market, handling wet labels, tube and box wraps primarily for the whisky market. The company also operates a Speedmaster SM 102-6+LYL and a CD 74-6.
